It has been confirmed that HP have released a new Firmware (February 2018) for any printers recently affected by non working compatible 953XL cartridges.

The new firmware file removes outdated supplies authentication measures as deployed in the latest firmware version, that may prevent the printer from working with certain ink supplies that contain non-HP security chips. Please note that even with this change HP cannot guarantee the quality or reliability of non-HP supplies.
